CAR-AXLE-JOURNAL-ZBOX PACKING.

Specification of Letters Patent.

Patented July 11, 1911.

Application filed December 3, 1909. Serial No. 531,272.

To all whom it may concern: I

Be it known that I, CHARLES C. HOWE, a

- citizen of the United States, residing at' Vyoming, in the county ofWashington and State of Rhode Island, haveinvented a new and usefulImprovement in Car-Axle-Journal-Box Packing, of which the following is aspecification.

My invention relates to a fibrous lubricating and anti-friction packingfor car journals: its specific object is to produce a packing which iselastic, and possesses lubricating and anti-friction qualities peculiarto itself. This I accomplish by a packing consisting of strands ofwoolen yarn thoroughly coated or filled with finely prepared flakes ofmica; the mica being preferably mixed with the woolen stock before it isspun into yarn, to insurea thorough incorporation of the wool and mica.This mica charged yarn is mixed with an elastic material such. asTampico fiber, to give it resiliency, and keep the oil saturated yarn incontact with the journal.

In the accompanying drawing which ex exemplifies the packing, thestrands of yarn are shown at 9, with the Tampico fibers at 10.

It is impossible to represent in a line drawing, the fine flakes of micawith which the yarn is charged.

It is now universally conceded that for lubricating the present type ofcar journal, oil saturated woolen yarn is the most reliable. Bycombining and mixing finely prepared mica flakes with the woolen yarns,the lubricating qualities of the packing are greatly increased; thefiber mixed packing being held in constant contact with the journal, onto which the fine flakes of mica are continually being fed with the oilfrom the yarn. These mica flakes will fill any inequalities on thebearings, and create a surface smooth as glass; thus obviating allfriction and heat resulting therefrom.

The enduring qualities of mica are several times greater than oil orgrease, and it is not affected by changes of temperature.

I claim:

The herein described combination of mica charged woolen yarn,intermingled with Tampico fiber, substantially as described.
